By referring to the drawings it will be seen that Figure 1 (section A) is the usual telephone subscribers station, with the circuit (a) connecting the subscriber's lines to the circuit (e) Figure 6 0f the invention. Section B represents the street lines to (section C), the sub-station line circuit at the usual telephone central oflice multiple switch-board, where I0 is the line lamp relay operated by the central oifice battery i I actuating the armature l2 to close the line lamp signal circuit, lighting the line lamp signal l3 when telephone sub-station circuit is closed by the operation of the protective signal system, producing signal impulses at the telephone central office multiple switch-board.

- In Figure 2 an alternate circuit arrangement is provided for those telephone central ofilces using a line lamp cut-out relay system, or the automatic switch-board system, showing the sub- A) with the circuit (b) connecting the subscribers lines to the circuit (c) Figure 6 of the invention, where (section B) represents the street lines to (section C) the line "circuit at the telephone central ofiice multiple switch-board, where the additional relay circuit (1) is connected to and in front of the switchboard installation, with relay operated by battery l5 actuating the armature IE to close circuit lighting signal lamp l1, when the telephone substation circuit is closed by theoperation of the protective signal system, producing signal impulses at a separate signal-board installation, for the reception of the protective signals of the invention here-inafter described. A battery source of power common to the central ofilce switch-board and cenmay be substituted for battery IS in the circuit (1).

The single wire (ground return) system illustrated in Figure 3'anticipates an independently operated system with the circuit (0) connecting v to the circuit (e) Figure 6 of the invention, where (section A) is the subscribers station, (section B) is the street lines to (section 0) the independently operated central office signal-board installation, where the relay l8 and thebattery I9 actuate the armature -20 to close the lamp signal circuit, lighting the lamp signal 2|, by use of a common ground return 22,

producing signal operated central the protective signal system, impulses at the independently ofllce signal-board.

The double wire system illustrated in Figure 4 anticipates an independently operated system using polarized relays to permit a greater number of subscribers to utilize a single circuit, than that permitted in the single wire (ground return) system, with the circuit (d) connecting the subscribers lines to the circuit (e) of the invention Figure 6, where (section A) is the subscriber's station (section B) is the street lines to (section C) the independently operated central ofiice signal-board installation, where the relay 23 and the battery 24 actuate the armature 25 to close the lamp signal circuit, lighting the lamp signal 26, when circuit ((1) is closed by the operation of the protective signal system,

central ofiice protectiveproducing signal impulses at the independently operated central omce signal-board.

This invention anticipates utilizing a number of subscribers stations on a single circuit, either with telephone operation, or independent operation, by means to vary the series of signal impulses transmitted, but has illustrated but one subscribers installation for each of the systems shown in Figures 1, 2, 3, and 4, to clarify these views. Additional subscribers stations may be connected to the street lines (section B) in all four views, as may be required.

As there are many variations and applications of the telephone. systems, and independently operated systems illustrated, it is understood that this description is given by way of example only, and that various modifications and other applications will readily occur to those skilled in the art.

In Figure 5 is shown a detail sectional view of one type of fire protective devices, which are a. part of the fire alarm circuit of the invention, reference character 21 in Figure 6, and illustrates an insulation support 21A, with the metal contact bar 213 supported thereon by a hinged fire alarm circuit (:r-11). Supported upon this contact bar 213 and on the insulation support 21A are the two contact points 21D, one point connecting to each side of the circuit (x-y) Figure 6, and held apart by the fusible plug 21E, which is composed of a low melting-point metal alloy or composition, melting at a predetermined temperature. Fastened at the end of the contact bar 21B, and the insulation support 21A is a metal coil spring in tension 211?, so arranged that when a predetermined temperature is applied to the fire,protective device 21, the fusible plug 21E will melt and allow the tension spring 21F to contract, and force the contact points 21D together, to close the fire alarm circuit (r-y), operating the signal distributor described in Figure 6.

A front view of the distributor or interrupter for transmitting signal impulses over circuit (e), and a schematic diagram of the various protective circuits, is shownin Figure 6, where a round insulated disc rotor 43 with gear teeth out along its edge, and with two metal inserts M imbedded thereon, and connected to collector brushes 45 contacting supporting shaft 46 to one side of circuit (e), the whole mounted on supports 50 with side of circuit (6), with a flexible metal contact brush 41 contacting the metal inserts M on rotor 43, as rotor 43 revolves, when the electric motor 48, with gear tooth drive 49 engaging rotor 43 revolves. Figure 6 also illustrates the fire alarm circuit (:c-y), the local warning gong circuit (10), and the actuating portions of the burglar alarm circuit (s-t), (p), and (o), where (a -z) is the primary circuit 42 excited by the usual l10-volt house current supply, exciting a low voltage current supply in the secondary circuit (:r-y) one side of the line (:r) connected to fire protective devices 21, and the other side of the line (y) connected in series thru the operating motor 48 to and thru relay 30 to fixed resistance 28, thru fixed resistance 28 to the opposite side of fire protective devices 21, forming the fire alarm circuit. Introduced across this fire alarm circuit (.t-y) is the local alarm gong circuit (w) where the alarm gong 29 is connected to the (at) side of the lines, and by the armature 3| of the relay 30, when relay 30 of a step-down transformer -tion on the opposite side -'-terially reduced frequency opens or closes the circuit 33, is the circuit with the is excited by the closing of circuit (c-y) by the protective devices 21, closes the alarm gong circuit (w), thru a single pole single'throw cut-out switch 32, operating the alarm gong 23, to serve as a local warning signal. Fire protective devices 21 are connected in parallelacrossflre alarm circuit (at-:1), and may be of any number required for adequate fire protection. Theresistance 23 introduced in series inthe circuit (:r-y) on the (y) side of the circuit, is for-the purpose of reducing materially the speed of the operating motor 43, when fire alarm circuit operate s,,thereby materially reducingthe speed,-for fire alarm signals, of signal distributing rotor 43, and transmitting less impulses over circuit (e), at a mafrom that used when the burglar alarm circuit is operating said signal distributor. It. will be noted that the fire alarm circuit (a:-y) is an open circuit, and becomes operative when actuated by the closing of the fire protective devices 21, and is responsive to said actuation continually irrespective of theconditions ofthe other circuits connected to the distributor for transmitting signal impulses.

The line (s) connected to the (11) side of the cirrelay 33 to attract its contact to the (a) side of the 5 energizing the pilot lamp 38, contacting the front contact of armature 31 and energizing the auxiliary circuit (1)), and energizing the, auxiliary armature 34 with 'its flexible contact 35, breaking circuit (s-t), and rendering said circuit (st) inoperative, irrespective of whether the burglar protective devices 51, or 59, are immediately contacted again, in the attempt to close the circuit (s-t), auxiliary circuit (9) continuing to the (1!) 10 side of the circuit (:c-y) and energizing said circuit. This movement of armature 31 of the supercult (3-11) and the line (t) connected to the (2:) side of the circuit (.r--1/) form the burglar alarm circuit, where a double-pole double-throw circuit switch 39, is introduced for manual operation on one side of the switch, and for automatic opera-' of the switch, where a subsidiary switch 40, operated by a mechanical or electrical time clock-work mechanism 4|, that has been adequately disclosed in numerous prior patents, and is common practice, or other means,

periods of time as pro-arranged by the subscriber v or the operating agency,.the line (s) continuing to the armature 34 with the, flexible spring 0on tact 35 of the auxiliary relay 33 andthrucontact 35 to the supervisory relay 33, thru relay 3! to the burglar protective, devices 53, 51, and 53, (Figure 11) these burglar protective devices connected as shown, terminating in the return line (t), to armature 31 of the supervisory relay 33, and to the switches 33 and 45. Also connected to the (t) side of the circuit (s-t) is the auxiliary circuit (1:) contacting the front contact of armature 31 a of supervisory relay 38, continuing to and thru the auxiliary relay 33 to (11) side of the circuit (H) as shown in Figure 6. Also introduced across the circuit (s-t) contacting the back contact of armature 31, when armature 31 is attracted by supervisory relay 38, upon excitation of said relay pilot lamp 36, energizing upon closure of circuit (s-t), to indicate to the subscriber, that the burglar alarm system is in an operative condition. The flexible contact 35 in the armature 34.01 the auxiliary relay 33 is provided, to allow a lapse in the movement of said contact 35 to prevent breaking contact oi the line (s) with said contact 35 of saidarmature 34, so that supervisory relay 38 becoming excited at the instant that auxiliary relay 33 does, upon closure of said circuits by either. switch 39 or switch 40, will attract its armature 31 before flexible contact 35 of armature 34 has broken contact with the line (3), this action of armature 31 breaking contact with auxiliary circuit (9), thereby de-energizing the auxiliary relay 33.

when the burglar alarm circuit (s--t) is opened by the breaking contact of any of the burglar protective devices, 51, or 59, supervisory relay 33 becomes de-energized, releasing back contact of armature 31, opening the circuit (0) and decircuit.

visory relay 33 also energizingthe alarm relay 3! in circuit (1!) to attract its armature 3| contacting back contact thereof, with the local alarm gong circuit (w) and actuating alarm gong 23, when switch 32 is in a closed position, the circuit (:c-y) efiective upon aforesaid energization, operatesthe motor 43 at its normal speed, rotating the distributor for transmitting signal impulses over the circuit (e) to the various central ofllce signal-boards illustrated in Figures 1, 2, 3, or 4. It will be noted that the burglar alarm circuit (s-t) is a closed and excited circuit when in use,.and becomes operativewhen the circuit (s--t)' is opened by the releasing contact of any of thevarious burglar protective-devices, 51, or 59. A local battery source of current, to excite these protective circuits, may be substituted for the step-down transformer 42, when there are no 3" local electric power lines available for use.

A front view of an alternate distributor or interrupter for transmitting signal impulses, is illustrated in Figure '1, where a different arrangement of the metal inserts 44 spaced at difl'erent intervals on, the rotor 43, than that shown on the rotor in Figure 6, allows this rotor to transmit a differ ent series of signal impulses over the common circuit (e), for the purpose of transmitting series of signal impulses distinctive to each a number of subscribers are connected a single There may be various combinations possible, allowing the various rotors, each trance mitting an individual series of signal impulses, to

use a common circuit for actuating the central 4.:

ofllce signal-board. A view taken at right angles to the view shown in Figure 7 is shown in Figure 8, where the relationship between the motor 43, the gear tooth drive 43,

50, together with the collector brushes 45, the con- I tact brush support 5| and its contact brush 41, are i all mounted upon the insulated base 53 as illustrated in the drawings.

A means for permitting windows to remain 55 open, for necessary ventilation, but to still be protected against unauthorized entrance, is shown in Figures 9 and 10, where the burglar protective device 59, Figure 11D is installed in a predetermined position on the interior side of a double- 9 hung window .jamb, and illustrates an insulation support 55, upon which is mounted two flexible. metal, spring prong contacts 56, said combination fastened to the window jamb by screws, and connected to the circuit (s--t) as shown in Figure 55' 11D. Instaled on the meeting rail 53 of the window, is the contact bar 54. Said metal plate contact bar 54, when contacting the flexible spring prong contacts 56, closes the burglar alarm circuit,

but any movement of the. window meeting rail in either direction, releases contact thereof, and

opens the burglar aarrn circuit (s-t), operating the burglar alarm signal system. An additional protective device 59 is installed at the Junction of the window meeting rails, when window is subscriber when 40 the insulated rotor 43 with its supports a0 closed, to'provide protection against opening window when ventilation is not required, as shown in FigureilD.

-' The connections, installations, etc., of the various burglar protective devices 5?, 58, and as, is illustrated in Figure 11, showing the installation for doors required to be protected, Figure 11A, the installation for protection of casement windows, Figure 1113, and also for double-hung windows, Figure 110, and anladditional installation for double-hung windows required to remain open for the necessary ventilation desired, but to still be protected against unauthorized entrance, Figure 11D. Casement windows required to remain open for ventilation, would require installed a protective device 51, mounted horizontal at the base of the inside roll screen, and contacting by the pressure exerted by the screen, similar to the sill protection of the normal double-hung window, as illustrated in Figure 110. There may be as many of these various installations as will be required to adequately protect the subscriber at all times. Protective device 58 is connected across the leads to protective device 51, Figure 113., to permit authorized entrance or exit thru the protected doors, when protective device 58 is closed and the burglar alarm system is in an excited condition, by means of a key lock switch on the door, manually operated on the inside and operated by key means on the outside, this means locking the protective device 58 in an open position from the outside when required, permitting the releasing contact or the'protective device 5? for operating the burglar alarm system upon unauthorized entrance through said protected doors.

The burglar protective devices 51 are illustrated in detail in Figure 12, by a sectional view, and in Figure 12A by a top view, where a flexible, metal,- spring contact 60, extending over and contacting another metal contact BI, when pressure is applied, and is installed at the interior sill and head sections of double-hung windows, and at the interior jamb sections of casement windows and door openings, said devices releasing contact andopening the burglar alarm circuit (s-t) upon release of said pressure when windows or doors are opened. When window and door openings are closed, the jambs or side rails of said doors, or said windows apply pressure to the contacts iill,contact ing contacts 6|, closing them, and completing the burglar alarm circuit (set) thereby.

A means for locking the burglar alarm circuit (s-'-t) to ,prevent unauthorized entrance, but

allowing authorized entrance by the subscriber is illustrated in'Figure 13 by an interior front view 'of the installation'of burglar protective device til,

Figure 11A, and in Figure li-by a sectional view of this protective "device 58, showing the relation ship between the various parts, and in Figure 15 by a sectional view taken at right angles to the the view shownin Figure 14, at the inside door line, to'show the back oi this device and its connection with its lock mechanism, where the insulated rotor switch 63, with the metal contacts 64 imbedded thereon, and connected together, make and break contact with the spring contacts 55, on the binding posts 66 connected to the burglar alarm circuit (s-t) as shown in Figure 11A. The insulated rotor 63 has a projecting knob for manually opening. and closing this switch from the interior side of the door 15. The binding posts 66 with the spring contacts 85, contacting the rotor contacts 64-, when switch is closed, are supported'on a fixed insulated plate 62, this plate holding the '.key switchassembly together by means of the studs (ill, and fastened to the door W by wood screws as shown in the drawings, The rotor 63 has an extended prong it, acting as a stop against the studs 5?, permitting a one quarter revolution of the switch only. Inserted thru the door 15 is the usual tumbler type key lock 6E, and the exterior key plate ll, with the tumbler barrel ill and the tumblers 6:5, and the key l2 to lift and align the tumblers, except that tumbler barrel ill has its inside end shaped as shown in mire alarm system operating The fire protective devices'il are installed at various locations tln-u-out the building to be protected, for example, there may be a fire protective device 2? installed at each end of the basement, one installed at each end of the first iioor, one installed at each end or the second floor, and one installed at each end of the attic floor, and in such other locations as are needed where increased fire hazards may occur. Upon a tire breaking out, for instance in the basement or the building. the temperature therein will until it has reached a point suifficient to melt a. e fusible plug 27E of the fire protective device nearest the source of the heat, closing the contacts 211D, closing said fire alarm circuit thereby, energizing alarm relay 3d, closing the local alarm gong circuit thereby and actuating the lol alarm gong 29, also operating the motor fill oi the signal distributor at a predetermined reduced speed, by reason of the resistance 28 introduced in the circuit, the operation of the signal distributor in turn closing and opening the external line circuit (e) to the line signal lamp at the central omce signal-board of the operating agency, flashing signal impulses on and off at a predetermined frequency and sequence at this signal-board. The signal-board operator on duty at the operating agency, identifying the type of signals by the reduced speed received (for fire alarms) and identifying the location of the signals by their sequence, notifies, by vocal telephone means, or other means, the local fire department of the fire alarm warning, and its exact location.

The burglar alarm system operating The clock mechanism ill closing the switch w and thereby closing the burglar alarm circuit,. excites said circuit for a predetermined time, until another predetermined time, when it actuauthorized entrance, or burgl occurs, either thru window openings, or door openings, of the protected building, burglar protective devices 51, or 59 break contact, opening the burglar alarm circuit (s--t), lie-energizing the supervisory relay 38, and releasing the armature 37, to contact and energize the auxiliary circuit (1:), energizing auxiliary relay 33, attracting its armature 34, thereby, and rendering said burglar alarm circuit inoperative, irrespective of the later contact of the protective devices, in an attempt to close that circuit (s-t), also energizing the alarm relay 30, closing the local alarm gong circuit (10), actuating the local alarm gong 29, and energizing the motor 68 of the signal distributor at its predetermined normal speed, the operation of the signal distributor in turn closing and opening the external line circuit (e) to the line signal lamp at the central omce signalboard of the operating agency, flashing signal impulses on and oil at a predetermined frequency and sequence at this signal-board. The signalboard operator on duty at the operating agency,

identifying the type of signals by the normal speed" received (for burglar alarms) and identifying the;

location of the signals bytheir sequence, notifies,

local police department of the burglar alarm warning, and its exact location. By operating the manual switch 39, to cut out the clock-actuated switch 40, the burglar alarm system may, be placed in an operative condition continuously, during the prolonged absence of the subscriber, by lockswitch means, as previously described in the speciii'cation.
